| Software notes | The system is based on a proprietary interface featuring a built-in 5-inch TFT screen. The firmware manages preset synergic programs (up to 27 lines) for various combinations of wire, gas, and thicknesses, facilitating the setup of welding parameters via a single knob control. It includes a memory function to save and recall up to 10 customized jobs. There is no wireless connectivity or external cloud interaction, nor does it support PC or smartphone software. All functionalities remain strictly manageable from the control panel of the welder. | As a step-regulated transformer welding machine, it features no management software or digital interface. Parameter control is purely electromechanical via selectors on the front panel, providing 10 positions for voltage adjustment along with potentiometers for manual regulation of wire feed speed and spot-welding time. |
